Title: Improvements relating to etched sheet metal pattern members
IPC: B41C1/14
Filed: 1959-06-10
Abstract: 890,067. Etching; transfers; transferring designs; stencils. C. & H. SUPPLY CO. June 10, 1959 [Oct. 7, 1958], No. 19947/59. Drawings to Specification. Class 100(2) A method of making a patterned aluminium member free from supporting background comprises forming an oxide film by anodizing on one or both surfaces of a sheet of aluminium, applying a resist design to one of the anodized surfaces when both surfaces are anodized, or to the unanodized surface when only one surface is anodized, applying a protective layer resistant to attack by acid or alkali etching solutions to the surface to which the design is not applied, subjecting the resulting assembly to etching to remove the oxide film round the resist design when such film is present, immersing the member in an etching solution to remove the metal round the design, and thereafter subjecting the assembly to an etching solution to remove the exposed oxide adjacent the protective layer. The resist design is inverted. After etching, the resist is removed by solvent immersion. The exposed surface is coated with adhesive, and with a temporary protecting sheet which is removed before use. The adhesive-coated surface is then applied to a surface of an object to receive the pattern, and the protective layer is removed. if the design is to form a stencil, it would not be applied to an object. The oxide layers may be etched with hydrofluoric acid and the metal with 10-30% hydrochloric acid or sodium hydroxide solutions at elevated temperatures. The oxide layer or layers may be pigmented.

Title: Process and apparatus for electrolytically oxidizing or reducing substances
IPC: C25B3/23
Filed: 1921-07-28
Abstract: 188,042. Thatcher, C. J. July 28, 1921. Electrolytes, circulating and agitating; authraquinone, obtaining.-In a process for electrolytic oxidation, spent electrolyte is passed through the cathode chambers to induce a reduction, the substance to be oxidized is disresolved or suspended in the reduced electroylte, which is then passed back through the anode chambers and the oxidized product removed. In a process for reduction, the direction of flow is reversed. The apparatus shown is suitable for the oxidation of anthracene to anthraquinone. Spent electrolyte consisting mainly of dilute sulphuric acid and sodium and chromium sulphates is. admitted from a tank 1 to the cathode compartment of the first cell 2 by a float valve 4 and passes to successive cells through pipes 6. During the passage most of the free acid passes through the diaphragms into the anode compartments and sodium bichromate present is reduced to sodium and chromium sulphates. In the last all the electrolyte passes by a syphon 7 including a regulating valve 10 to the anode compartment and finely divided sublimed anthracene made into a paste with water or preferably with a little of the catholyte from the last cell is added from a tank 8. The electrolyte and suspension pass to successive anode compartments by syphons 9, and then to a tank 11 provided with a heating coil 12 and a stirrer 13 and finally to a filter from which the filtrate is returned to the tank 1. The cells may have heatinsulating coverings and the current-density is so chosen that the temperature of the electrolyte is about 75 C. where the anthracene enters and 95 C. in the last cell. The passage of the anthracene through the apparatus takes about 10 hours. Stirrers are provided in the anode compartments, the catholyte being agitated by evolution of hydrogen. The cells are connected in series or in series-parallel.

Title: Purity monitor for the visual inspection of the purity of flowing liquids
IPC: G01N15/06
Filed: 1963-05-22
Abstract: 967, 887. Turbidometers. CALTEX CENTRALE LABORATORIA N.V. May 22, 1963 [May 24, 1962], No. 20356/63, Heading G1X. A liquid, such as fuel being supplied from a reservoir through a conduit 1, Fig. 1, pump 2, filter 3 and manifold 4 to aircraft fuel tanks is inspected as to its solid matter content by passing a proportional sample stream through filters 7, 8, in series and visually comparing the filters. Each filter may be a cup shaped holder in which filter paper is releasably held by a split ring and is observable through a cover glass. In a more elaborate arrangement, Fig. 3, fuel enters a block 31 through channel 45, passes to a pressure regulator (not shown) housed in a recess 35 and flows through passage 47 to a bore 41 housing a rotatable plug 43. With the plug 43 in position I, as denoted by the finger 54 of an operating knob 55, the fuel flows from passage 47 to bore 51 and thence through bores 48, 50 to passage 56 leading to a first filter chamber (not shown) screwed on the raised platform 32 and then through passage 66 to the second filter chamber (not shown) screwed on platform 33. The fuel leaves through passage 67 and outlet 40. At the same time fuel flows from bore 50 through passage 57, a throttling valve (not shown) in bore 42 and passage 57<1> to act on a piston 38 to force it,against the action of a spring (not shown) until it eventually contacts cover 39 to close outlet 40 and end the sampling. The position of piston 38 at any time may be seen by the movement of a ball 69 in a slot 68 and acted on by a piece of magnetic material carried by the piston 38. If the sampling has to be interrupted before it is complete, knob 55 is rotated to position II and all passageways terminating in bore 41 are closed. At the completion of sampling, knob 55 is rotated to position m so that passage 47 is shut off and the spaces on both sides of piston 38 are connected via passage 72,bores 52, 48, 49 and passage 71. The piston 38 then returns to the left under spring action and the filters may be replaced. Position IV is for checking. In this position, if the throttling valve in bore 42 is replaced by a pressure gauge the pressure regulator in bore 35 may be adjusted, and piston 38 rapidly moves to its cut-off position by liquid flowing through passages 45, 47, bores 51, 48, 53, and passage 72. An image of half of each filter may be projected so that both halves appear side by side by apparatus as in Fig. 5 (not shown).

Abstract: 1492675 Exhaust gas recirculation; injectors FRANCAIS ETAT 14 May 1975 [15 May 1974] 20438/75 Heading FIB and F1E The ratio of air delivered by the compressor 5 to that of exhaust gas recirculated by the ejector pump 13, in a power-plant comprising a turbocharged diesel engine 1 having a by-pass line 7 and an auxiliary combustion chamber 8, is controlled so as to raise the temperature of the compressed air at starting and low load in response to the pressure output of the compressor and the temperature of the air drawn into the compressor. The flow of air and exhaust gas may be controlled conjointly, Fig. 4, or alternatively one of the two flows only may be affected, Fig. 1, for exhaust, Fig. 3, for air. Where necessary means 31 for preventing backflow of air down the exhaust transfer pipe 16 may be provided, Fig. 3. In Fig. 4, the axially moving cone 33 conjointly inversely varies the flow-paths for air and exhaust gas flows (22, 27) in response to compressor pressure on piston 36. Calibrated air bleed 40, spring 39 and the compressor air intake temperature sensor air bleed 41 determine the pusition piston 36 takes up. At high compressor output, the cone 33 closes the exhaust gas flow-path 27 completely by abutting the walls 34. The valvemember 42 acts as an adjustable abutment when the spring 39 is fully compressed. Fig. 2, (not shown) illustrates a flap operated variable air flow-path, which operates in a similar manner to completely close the exhaust flow-path. An alternative arrangement, Fig. 8, has a check-valve 68 which is held closed by spring 66 when the air-flow is unrestricted by the body 29a. On moving the body towards the ejector nozzle 22, air bleed 61 is opened and the differential pressure set up across the 'leaky' piston 65 cause valve 68 to open. The power unit may include an air cooler 45 in the induction line 2, a by-pass line 46 and a valve arrangement 47 preventing air-flow therethrough when the flow control means 19 permits exhaust gases to be recirculated.
